When you click on the diplomacy button you see a list of countries which can be sorted by country name, coalition, player name, number of provinces, their relation, number of victory points, activity, your relation, and devices. There is also an information button for each country to drill down into player profiles. In the player profiles one can see additional information such as the player's experience level, Kill/Destroy ratio, # of known units, who they are at war with, etc.

It would be really helpful to have some of that drill down information columnized on the 1st screen in order to sort the list by them, for example you could see a list of all players in order of their skill level, or K/D ratio, # of known units, and at least how many countries with whom they are at war. The data already exists and can be seen by drilling down but there is no way to sort by it.

In addition it would be helpful to list players by proximity, perhaps a filter to include/exclude players for given regions, or by distance from yourself.
